| 摘 要： | 对常规的带有棱镜对色散补偿的四镜腔固体克尔透镜锁模激光器,现有文献只考虑晶体的材料色散而忽略了晶体的斜入射所带来的角色散.首次给出了由于在晶体处的斜入射,不同波长的光线在该激光谐振腔中的振荡回路.给出了考虑晶体处的斜入射后二阶、三阶色散的解析表达式.并计算了斜入射带来的对激光晶体和棱镜对系统二阶、三阶色散的影响.

| Abstract: | In mest articles, the material dispersion of crystals was and the angular dispersion resulted from the oblique incidence on the laser crystal was ignored, because all the rays with different wavelengths are regarded as the the same path in the laser crystal for the standard four-mirror-cavity KLM laser.In this paper, we present the oscillating loops of the rays with different wavelengths in the resonator and give the analytical expressions of the second-order and third-order dispersions resulted from an oblique incidence on the laser crystal. Also the variations of the second-order and third-order dispersions for the laser crystal and the prism-pair system are calculated. |

| Keywords: | oblique incidence angular dispersion second-order dispersion third-order dispersion |
